Speaker Cable Set with an individual positive & negative Wire - Overview wanted

[tiefbassuebertr]

First happy new year for all !!

Speaker cable set with an individual positive cable and an individual negative cable for each channel delivers the highest sonic quality - at least from my view. Therefore this version is for me the most ultimative design

I guess, that the main reason therefore is the nearly non-existent capacity (the influence of the residual inductance is not audible and thus negligible - so I think)

I haven't heard about any disadvantages from this kind of speaker wires and therefore I want to have a line-up of such commercial available wires, which are not often to find.
Here examples of such cable devices, which I just have found on the web:

But I want to know more both vintage and currently available models - thank you very much.

The issue with widely spaced speaker cables is not inductance but interference pickup. The bigger the loop area the bigger the pickup. The interference signal is dumped at the amp output, and then the feedback loop sends it straight to the input. Some amps will cope; many will not, and demodulate any RF present.

This could be another example of cables with significant design flaws sounding 'better' to some people because they misinterpret the interference as extra 'detail' in the music.

Reducing that interference injection into the -IN pin of the power amp is why we need some RF attenuation at the speaker terminals.
Cordell now shows a preference for the Pi version of the Thiele output network.
Few others have changed over to this Pi network, to attenuate the RF that pollutes our homes.

delivers the highest sonic quality - at least from my view.

Try doppelblindtest against standard zip cord to see if you are just imagining or if it's real.

They don't say what happens after the 300 hour break-in. Why would they mention it?

If the connected loudspeakers have a low impedance at high audio frequencies (think Apogee and other true ribbons) then cables with high loop inductance could soften the treble.

For 8 ohm speakers I like this 2SO cord, https://www.mcmaster.com/#7081K17
ultraflexible with hundreds of tiny strands, rubber insulation, 10 ga
$23 for 10' FOB aurora OH USA
I find 20' of 16 ga zip cord causes fast vibrato on top octave piano, using my 8 ohm SP2-XT speakers and my ST120 amp w/ djoffe idle current control modification & NTE60 output transistors. 10' of 10 ga SO cord doesn't have the vibrato. Piano, obviously, doesn't produce vibrato. There is a top octave solo piano track on Peter Nero Young & Warm & Wonderful album.
Your amp and speaker results may vary. I don't have any 14 ga zip cord to compare to as conarski recommends being just as good. the 3SO-10 cable I'm using was free out of the dumpster at work, so the price is excellent.
I do have a zobel on the back of the speaker jack of the amp as suggested by the dynaco "TIP mod", and the 12 turns speaker feed wire around the output capacitor part of the original design. RF interference is no longer a problem.
